Sarah Jessica Parker & Matthew Broderick’s Son Turns 15

With a throwback photo, the proud mama, 52, posted a heartfelt message for her teen son.

“Happy birthday My first born My only son 15 years old Gosh, I thought I knew what love was back then. I hadn’t a clue. X, Mama,” she wrote.

Last month, Parker settled rumors about a third Sex and the City movie.

“It’s over… we’re not doing it,” the actress, who portrayed Carrie Bradshaw in the popular TV series and movies, told Extra.

She went on to explain, “I’m disappointed. We had this beautiful, funny, heartbreaking, joyful, very relatable script and story. It’s not just disappointing that we don’t get to tell the story and have that experience, but more so for that audience that has been so vocal in wanting another movie.”

That said, Kristin Davis is still holding out hope.

“For us, it’s hard because we’ve been doing it a long time and it’s been an amazing journey. We have a franchise that we’ve built over 20 years, almost, with four leading women, which is really unheard of. So for us I’m just grateful. I know my costars are grateful as well that we have the fan support, that we have each other, that we love each other,” Davis told E! News. “Maybe we’ll figure out something to do, I don’t know, it would be great. I just feel like it’s a positive thing all the way around. I’m sad that we’re not doing the movie but at the same time, I love the support so much and I’m so grateful for it.”

Meanwhile, Kim Cattrall recently made an appearance on Piers Morgan’s Life Stories and said she’s “never been friends” with her famous costars.

“We’ve been colleagues and in some way, it’s a very healthy place to be,” she added.

Cattrall also addressed rumors that she turned down a third film because she wasn’t being paid enough.

“I never asked for any money,” Cattrall said. “I never asked for any projects. To be thought of as some kind of diva is absolutely ridiculous.

Sarah Jessica Parker and husband, Ferris Bueller’s Day Off star Matthew Broderick, welcomed their only son on Oct. 28, 2002.

Parker and Broderick are also parents to 8-year-old twin daughters Tabitha and Loretta. In April, the famous family made their red carpet debut together at the opening night of Broadway’s Charlie and the Chocolate Factory in New York City.
